摘　　要：根据我国《GB/T 28264—2012》的要求,我国六十吨以上的起重机都将安装起重机械安全监控管理系统。根据对起重机的研究发现,由于PLC功能的逐步完善,大多数必须的监测参数是可以直接在PLC（Programmable logic Controller,可编程逻辑控件）系统上获取的。本文为了开发起重机监控系统,主要研究了西门子S7-300与PC机之间的通信原理与过程,成功地对PLC与VC＋＋进行了对接,并通过VC＋＋对PLC里面的数据进行提取,转换成为实时显示的数据,为以后的数据存储开发,调取打下了良好的基础。According to the requirement of Chinese ＂GB / T 28264-2012＂,we must install crane safety monitoring and management system for more than sixty tons crane. According to findings of studying crane, owing to the gradual improvement of the PLC functions, the most of the monitoring parameters can be directly obtained in the PLC system. In order to develop crane monitoring system, we mainly studied the principle of communication process between Siemens S7-300 and PC machine. The docking of PLC and VC ＋＋ was successfully carried out, the PLC data were extracted by VC ＋＋ for the PLC, and were converted into real-time display of data. Studying results will obtain a good foundation for the development of data storage for later.
